IMPROVEMENT IN SPIN NING-FRAME.

'O-(.)-0 The Schedule referred to in these Letters Patent and making pm of the sama.

To all whom it may concern Be it known that l, H. BEAUMONT Bmees, of the town of Clarksburg, in the county of Berkshire, in the Commonwealth of Massachusetts, have invented a new and improved Spinning-Frame for spinning wool, cotton, or other fibrous substances; and I do hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings.

The nature of my invention consists in the mode of delivering and drawing the roving and winding the spun yarn on to the continuously-revolving spindle di: rectly-from the delivery-rollers. It is accomplished by having the delivery-rollers placed on rocking bars, t0- gether with the drum which supplies the I'ovin g to the delivering-rollers. These rocking bars are moved by an eccentric, or crank, or other device, away from the spindles, and back, causing an oscillating motion alternately to and from the spindles, the roving being drawn .as the bar moves from the spindles, and the yarn being wound on the continually-revolving spindles as the bar moves toward them. As the rocking bar begins to recede from the spindle, a certain amount of roving is deliveredv and drawn, thus continually delivering, drawing, and winding on to the spindle or the bobbin on the spindle.

In order to allow the yarn tobe wound on to the spindle, I use a lifting-bar, to raise the thread ofi` from the points of the spindles as the rollers are moved toward the spindles, and the bar is again depressed at the proper time, to allow the threads to wind around the point of the spindle, preparatory to the roving being delivered and drawn, as before stated.

This invention is not coniined to the employment of a rocking bar, for the saine result may be accomplished by moving the rollers and roving to and from the spindles on a carriage, or the carriage may carry thel spindles to and from the rollers; but, in the accompanying drawings, I show the rocking bar, as being most simple, and easily described.

In the accompanying drawing- Figure I represents a vertical section of a spinningt'rame.

Figure II represents a front View.

On the frame A, on top of the rocking bars S S, is mounted a drum, B, which holds the roving; also the delivering-rollers O D E, which are held in their bearings. ,I

A rot-ary motion is impaited from the cylinder H to the rollers O and D and the drum B by gearing or other suitable mechanism, and the roller E liesonthe top, and between the rollers O and D.

The roving passes from the drum B, in the usual way, n nder the rollers E, and over the rollers C D, to

the spindle F, which has a continuously-revolving 1110-.

tion in one direction, and the rollers are moved to 4and from the spindles, alternately delivering and drawing, and, in connection with the lifting-bar G, winding the yarn on to the spindle or the bobbin on the spindle, in the usual way, by the ringV and traveller, or flier, or their equivalent, the whole as described and shown by the drawings. v

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In combination with the movable yarn-delivering rollers and the continuously-revolving spindle, the lifting-bar, for lifting the yarn from the point of the spindle prior to winding the same on to the spindle, substantially as described.

2. The lifting-bar, in combination with the continuously-revolving spindle, for the purpose of lifting the yarn olf from the point of the spindle, and holding it up while it is receiving the twist and being wound on to the spindle, without reducing the speed thereof.
